# Tower

> Taffy pack: a fidget tower of rounded candy plates, with a lilac base, a clear glass block with a mint core inside, butter, sky and a rose cap, ringed by an apricot hoop. A ripple of twist runs up it, and every seven seconds it cascades a quarter turn, layer after layer, as the hoop spins the other way. A tap sends a faster cascade. Raymarched in WebGL.
